Fun while it lasted

This app was great, but it was abandoned by the developers. It stopped working with Gmail and no updates in 5 years.

Orphaned: no reply from tech support; wouldn’t launch until I uninstalled/reinstalled

UPDATE: Deleting the app and all of its local data, then reinstalling fixed the problem on both iOS and iPadOS.

The iPad version doesn’t know the keyboard key locations in landscape mode any more, but still does in Portrait.

This has been such a great app since I bought it for all my platforms years ago. Unfortunately, the iPad/iPhone versions stick on the splash screen then timeout and exit after 5 seconds now. The macOS version continues to work like a champ. Hoping the developer reads this and fixes whatever is preventing the iOS version from launching—they haven’t responded to any emails to their tech support. Perhaps it calls home to a server which is no longer online?

FAQ

What does Unibox do?

Unibox is an email application designed to simplify inbox management by grouping all your emails by sender. This allows you to easily see all conversations and attachments exchanged with a specific person in one consolidated view, making it much easier to keep your inbox clean and organized.

How does Unibox help clean up my inbox?

Unibox helps clean your inbox by allowing you to quickly identify and delete multiple emails from the same sender with a simple swipe gesture. This is particularly useful for unsubscribing from or clearing out newsletters and notifications that you no longer need.

What email providers does Unibox support?

Unibox is compatible with all email providers that support the IMAP protocol. This includes popular services like Gmail, Hotmail, Outlook.com, Live.com, Yahoo, Office365, and Exchange servers with IMAP enabled, as well as many self-hosted servers.

Is Unibox available on other platforms?

Yes, in addition to its mobile application, Unibox is also available for Mac users. This allows for a consistent email management experience across different devices if you use both a mobile device and a Mac.

What is the cost of Unibox?

The application is free to download and use, but it does include in-app purchases. This suggests that while core functionality is available for free, certain advanced features or customization options may require a purchase.
